GAGE FOR PAPER-CUTTING MACHINES.

To all whom il may concern:

Be it known that l, GEORG E NELSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Gages for Paper-Cuttmg Machines, of which the following is a specification.

My invention relates to gages for paper cutting machines, and the object of the invention is to provide a portable gage for holding paper, strawboard, leather, or any of the other' similar material ordinarily used in the printers7 and bookbinders art, in any desired position relatively to the cutting knife.

I obtain my object by the mechanism illustrated in the accompanying drawing, in which Figure l is a perspective view of the complete device g Fig. 2 is a front view of a portion of a portable cutting machine, showing my portable gage in position thereon; and Fig. 3 is a fragmentary sectional view, taken transversely of the base for illustrating the preferred form of set screw and guide.

Similar numerals refer to similar parts throughout the several views.

In the preferred form of my invention here illustrated, the base 5 is adapted to stand in upright position, and is provided with two flanges, G, 6, extending at right-angles thereto. The lower flange is adapted to rest upon the table 7 of the paper cutter, and both ofthe flanges are adapted to rest against the permanent gage or grating 8 of the paper cutting machine.

To the front of the base 5 are hinged wings 9, 9, which are arranged to swing about an axis parallel to the path of the reciprocating knife l() of the paper cutting machine. In the construction here shown, the wings are hinged, top and bottom, upon separate lugs ll, but it is not essential that said wings have separate axes, for said axes may be co-ineident without departing from the spirit of the invention.

The means for adjusting the wings and .Fixing them in the desired position, is clearly illustrated in Fig. l, taken in connection with the fragmentary sectional view of Fig. 3. In this form of my invention, a rod l2 is pivotally attached to the upper edge of each wing. The other end of the rod carries a set screw or bolt 13 which passes through it and the slot I4 in the upper Harige (i. Beneath said flange said set-screw or bolt carriesthe nut l5, which, by preference, is square, and is adapted to slide within the channel 1G extending longitudinally in the upper flange G along slot 14.

f In the operation of the device, when it is desired to employ my portable gage for cutting paper or other Specilcation of Letters Patent.

stock upon an angle, the gage is placed upon the table 7 of the machine and moved up against the permanent machine-gage 8. The screws 13 are backed off, so that said screws and the nuts l5 may assume any position lengthwise of the upper flange 6. The wings 9 are then brought by the operator to the desired position to give the proper angle to the stock. The operator then tightens up the screws 13, thereby rmly securing the wings 9 in adjusted position. The stock may then be moved in position between and against the inner surfaces of wings 9, and when the knife descends it will cut the stock accurately. By employing my gage, an indefinite number of pieces of stock may be cut exactly alike, and the gage may be filled and the cutting operation repeated over and over again on fresh pieces of stock, with the certainty that the pieces will all be exactly alike. This is very desirable, especially in cutting small pieces of stock in triangular shapes. For example, book binders, in producing the corner leathers for binding books in what is known as half leather7 frequently have to handle a great number of small pieces, all of which are to be exactly alike. In reproducing pieces of this kind by the ordinary method considerable variation is apt to result. By employing my gage however any nnmber'of pieces exactly alike in form may be produced rapidly and without any particular degree of care or skill on the part of the operator.

In the preferred form the wings are pivoted upon separate axes as shown. As a result, the edges of the wings do not come closely together and consequently the corner of the paper to be cut may enter between the wings without hindrance. Moreover there is little opportunity for any foreign substance to become lodged in the corner ofthe gage and prevent accurate placing of the paper; and the device is also1 easier to keep clean. v

What l claim as new and desire to secure by Letters Patent is:

1. A gage for paper cutting machines comprising an upright base and two wings pivoted thereto about separate axes parallel to the path of the cutter of the machine.

2. A portable gage for paper cutting machines consistingl of a base adapted to rest upon the table and against the permanent gage of the machine, wings pivoted to said base upon different axes, the inner corners of said wings being separated from each other and means for setting said wings in desired position.

3. A portable gage for paper cutting machines having a.

base adapted to stand upright upon the table of the cutting machine and against the permanent gage thereof, wings pivoted to said base upon axes remote from each other, rods pivoted to said wings and adjustably connected to said base whereby Wings may be set independently of I each other at any desired angle.

4. A portable gage for paper cutting machines having a paper table and a permanent gage, said gage comprising a base adapted to stand upright upon the table, horizontal flanges on said base for abutting the permanent gage, the upper one of said anges being slotted longitudinally, Wings pivoted to said base, rods pivoted at one end to said wings, set Screws pivoted to the other end of said rods and E extending through said slot, and nuts on said screws beneath said flange for holding the parts in adjusted position.

lu witness whereof, I have hereunto subscribed my name in the presence of two witnesses.

GEORGE NELSON.
